Customize Course

• Items that are placed in the file [TMP]/macros/PGcourse.pl will affect the appearance of all of the problems in your course homework sets. Here are some examples:

• This snippet allows student to obtain a new version of a problem (after they have completed the problem correctly)

 $guest   = ($effectivePermissionLevel == -5) ;	####	practice user
 
 ####	Presume that faculty observers are given TA status (permission 5).
 $observe = ($effectivePermissionLevel >=  5) ;	####	TA or Professor (permission 10)
 
 loadMacros( "problemRandomize.pl" ) ;
 
 ####	Allow a Guest or Observer to always get a new version of problem.
 ProblemRandomize( when => "Always", onlyAfterDue => 0, style => "Button" )
 	if	($guest or $observe) ;
 
 ####	Allow everybody else (e.g., a student) to get a new version (for more practice)
 ####	after correct answer(s) to first (scored) version OR after the assignment's due date
 $when = (time >= $main::dueDate ? "Always" : "Correct");
 ProblemRandomize( when => $when, onlyAfterDue => 0, style => "Button" )
 	if	not ($guest or $observe) ;
 
 ####	Note: those two uses of ProblemRandomize reflect choices which can be made independently,
 ####	e,g,, you could invoke one and zap/comment-out the other.
 
 ####	Always allow observer or teacher to View Source Code for problem.
 ####			loadMacros( "source.pl" )	if	$observe ;
 ####	commented-out because extra setup needed by an admin with shell access
 ####	Note: PREP-2011 participants have professor status & can always invoke Edit Source.
